Time is 1967, before big block in pickups, what do you choose. Biggest six is 292, biggest V8 327. A magazine decided on doing a test on similar C 20''s with same trans, tires and axle ratio and throwing a camper on back. Results were interesting, V8 was a little quicker, but worse gas mileage. 6 performed better at lower rpms, with a little better gas mileage.
